PREFERRED

• Working knowledge of embeddings and vector representations like generating, storing, indexing, and querying embeddings (FAISS, Milvus, or equivalent)
• Familiarity with content-understanding models like image classifiers, object detection, OCR, NSFW detection, aesthetic scoring
• Experience with LLMs for data tasks like prompt engineering for annotation, data cleaning, or evaluation using LLM APIs
• Knowledge of generative AI like diffusion models, image generation, evaluation metrics (FID, CLIP score, etc.

).

Job Description:

Generative AI models are only as good as the data they consume. Unlike traditional data engineering, building data pipelines for generative AI requires orchestrating ML model invocations (content understanding classifiers, embedding models, LLM-based cleaners) alongside standard SQL-based transformations, all at billion-row scale.

This role sits at the intersection of Data Engineering and ML Systems. The Senior AI Data Engineer will own end-to-end data pipelines that don't just move and transform data, but enrich it through remote model inference, managing the systems complexity of async execution, capacity allocation, retry/fallback logic, and throughput optimization that comes with it. This is not a pure ETL-with-SQL role; it demands hands-on systems experience with distributed inference infrastructure.

Our team develops comprehensive data curation and evaluation solutions for image generation models across quality dimensions including visual quality, prompt adherence, identity preservation, naturalness, and visual text generation.

Job ResponsibilitiesMain ResponsibilitiesAI-Augmented Data Pipelines:

Design and maintain AI-augmented, large-scale data pipelines (billions of images) integrating traditional transformations with ML models (classifiers, embeddings, LLMs) for cleaning and annotation.

Remote Inference Orchestration:

Own the systems for remote ML model inference orchestration within pipelines, managing batching, retries, async jobs, and ensuring graceful degradation.

Feature Pipelines:

Build and maintain scalable pipelines for generating, storing, and serving vector embeddings, including nearest-neighbor index management and quality validation.

Data Curation at

Scale:

Source, filter, and curate training datasets using a combination of SQL and model-derived signals (e.g., aesthetic scores, NSFW classifiers), owning the end-to-end data flow and maintaining governance, quality, and compliance.

Additional ResponsibilitiesLLM-Assisted Annotation:

Design and operate pipelines that use LLMs and vision models for automated annotation of training data, including auditing workflows to measure and improve annotation model performance.

Tooling & Frameworks:

Contribute to shared tooling and frameworks that make it easier for the broader team to build AI-augmented data pipelines — e.g., reusable operators for model invocation, standard patterns for async job management.
